I made this shockmount for the D50 out of 1/8" x 3/4" aluminum stock (available at good hardware stores). The joint/pivots are 5/16" pop rivets. When doing the pop riveting I inserted shims around the rivet, so that the joint would be loose enough to pivot. The pivoting crosspiece lets you fold it flat for storage/transport. I had thought that I would need set screws to hold the crosspiece angle, but the joint is tight enough so that the set screws weren't needed. I drilled and tapped the crosspiece to go onto a 3/8-16 threaded stud (standard thread on photo light stands), I insert a reducter to fit 1/4-20 studs as needed. The rubber bands are the ones that the postman uses to bundle letters...they hold the d50 very securely, but provide lots of bounce.

Very nice +T.
Make sure you keep an eagle eye on the rubber bands as they perish and you know what may happen then :)
Perhaps you should look for some nice o-rings or something from a more durable material... Silicone wrist-bands perhaps, e.g.

or similar (http://www.yournameeverywhere.com/wristbands/Bands.html).
Thinking about an alternative to the riveting, perhaps a pair of wing-nuts on a short flat-head bolt/screw.

Fish - thanks for the idea about wristbands, handn't thought of that, know what you mean about rotting rubber bands. Fortunately, with the amount of junk mail I get, I always have a freshs supply. :P
Nice thing about pop rivet is that there's nothing to lose. Also, if you have the tool, a little easier than cutting threads with a tap. If I were going the screw route, I would use thumb screws rather than flat head screws, that way I could tighten down the angle without using a coin, or whatever. Thumbscrews are butt ugly, though.
